' SPECIFICATION forming part of Letters Patent No. 597,416, datedJanuary 18, 1898.

Application filed June 1, 1897. Serial No. 638,907. (No model.)

To all whom it may concern:

Be it known that I, SEYMOUR G. I-IULBERT, of the village of Geneva,county of Ontario, and State of New York, have invented new and usefulImprovements in Stove-Bases, of which the following is a specification.

My invention relates to an improved construction of that part ofheating-stoves which is termed the base and which contains the base-top,in which the grate and fire-pot are mounted and to which the lower endof the combustion-chamber is attached, and which base part also containsthe ash-pit and the ash-pit drawer and has an apron which roofs in theash-pit part of the stove.

As heretofore made stove-bases have been produced from several pieces,cast separately and mounted together, and they have also been producedby casting in one piece a downc-urved overhanging skirt together withthe base-top and ash-pit and so molded as to inclose the sides and thebottom and top of the opening formed in the base-front to receive theframe in which the ash-pit door is mounted. To improve uponthese oldermethods of constructing stove-bases, I form the base-top, the apron, andash-pit in one casting,with the latter so molded as to form the twosides and bottom of an open-top doorway for the ashpit door, and tocomplete the latter I employ a separately-cast top plate constructed toconnect at its ends with the base-top, with the ash -pit door -frameconstructed to connect with the sides and bottom of the opening and withthe separately-cast top plate, so as to overlap the top of the latter.As thus produced the integrally-formed base parts, consisting of theash-pit and the two sides and bottom of an open-top doorway for theash-pit door, the base-top, and apron, can be cast without the use of aspecially-made flask, and the contingency of occasionally losing acastin g in the sand is avoided, while the top part of the base dooropening when made separately and attached perfectly secures the parts,and in its connection it can be so applied as to correct such measure ofwarping as may have occurred in the cooling of the casting and thusfacilitate the mounting of the ash-pit door-frame and door within theopening formed to receive it.

Accompanying this specification, to form a part of it, there are threeplates of drawings, containing seven figures, illustrating my invention,with the same designation of parts by letter reference used in all ofthem.

Of the illustrations, Figure 1 is a front elevation of my improvedstove-base with the swing-down door of the shaker-openin g shown asclosed. Fig. 2 is a view of the same parts that are shown at Fig. l withthe swing-down door of the shaker-opening shown as open. Fig. 3 is aperspective of myim proved stovebase with the overhanging apron formingits down-curved exterior above the ash-pit formed integrally with thelatter and so as to produce at the front of the base the two sides andthe bottom of the opentop doorway for the ash-pit door. Fig. 4 is aperspective of the separately-cast top plate which, when in positionwithin the base, forms the top of the doorway, having its sides andbottom cast integrally with the base, and in this illustration shown asdetached. Fig". 5 is a perspective of the ashpit door-frame with what isits front shown as facing the view. Fig. 6 is another perspective of theash-pit door-frame with What is its inner face when in position withinthe base shown as facing the view. Fig. 'iis a perspective of myimproved stove-base with the separately-cast top plate of the ash-pitdoor-frame in position within the base, with the ash-pit door-frameinserted within the opening.

The several parts of the apparatus thus illustrated are designatedbyletter reference, and the function of the parts is described asfollows:

The letter A designates the ash-pit, having -the side walls WV, whichlatter, in connection with the bottom B, form the sink S in the ash-pitbottom, as shown at Figs. 3 and 7.

The letters G designate the apron of the stove-base, and this apron ispreferably circular in form in its lateral extension, and from where itunites with the top of the base it is made to project downwardly andoutwardly in curved contour, so that at its lower edge it will overhangthe ash-pit exterior.

The letters 0 designate the opening in the base to receive the ash-pitdoor-frame and door, which is located in the front of the base with thatpart of the latter forming the bottbm of the opening and designated at fhaving the rabbeted edge Z7 and that part of the base inclosing thesides f of the opening having the rabbeted edge U The letters Rdesignate bolt-lugs formed at each end of the base part forming thebottom of the opening 0, and the letters R designate a lug-seat 0rbolt-ear formed in the opening bottom f to project inwardly therefrom.

The letters Zdesignate ledges or shelves, of which there is one at eachof the upper corners of the opening 0, and each of these shelves orledges is projected inwardly over the opening 0 at the top of thelatter, and they are each rabbeted at Z where joined to the base-top,and at Z they are each rabbeted to the rabbeted edge 12 at each side ofthe opening 0.

The letter Z designates a lug which'is upwardly projected from the inneredge of each of the ledges or shelves with each of the latter providedwith a vertical bolt-passage a.

The letters P designate the separately-cast top plate employed toconnect with the base and inclose the top of the opening 0, and theletter E designates an upcast rim or flange formed on the inner edge -ofsaid top plate, the function of which rim or flange will be explainedhereinafter. At each of its ends this top plate is made angular at p and19 so that when applied to the base to complete the formation of theopening 0 by its insertion in and attachment to the base its angularpart 19 will abut against the rabbeted edge of the top T at Z at eachside of the opening, and the angular parts 19 of the top plate at eachend of the latter will abut against the rabbeted edge Z1 formed in eachofthe opening sides f The letter on designates stove-bolt lugs projectedfrom the outer'edge of the top plate P, through which lugs bolts arepassed to connect the ash-pit door-frame with the top plate, and theletters 0 designate bolt-passages in each end of the top plate P, whichwhen the latter is entered upon the ledges or shelves Z thesebolt-passages will register with the boltholes made in the ledges forthe insertion therein of bolts connecting the top plate P with theledges or shelves of the base, and thus complete the formation of theopening 0.

The letter F designates the frame of the ash-pit door, and the letter Ddesignates the ash-pit door, which is hinged at H to one of the framesides. This frame F at its sides f is given a contour corresponding tothat of the apron G, and it is made with an incurve I at its upper end,whereby when placed within the opening 0 its upper incurved edge willoverlap the outer edge of the top plate P to rest on the top of thelatter.

The letter E designates a ring part or flange which is upcast from theinner edge of the inturned top part Land which when the frame is inposition within the opening 0 this ring part or-flange E will join theends and complete the ring J, which is upcast from the base-top T, andthe upcast ring part or flange E of the top plate P Willbe in line withthe upcast ring part J which is also upcast from the top 'T inside thering part J, and so as to form with the ring part J theintermediatelyarranged annular groove g, invwhich the firepot of thestove is mounted.

The sides of the door-frame F when entered within the opening 0 willabut against the edge of the rabbet b and the bottom edge of thedoor-frame will abut against the edge of the rabbet 6 formed in the baseat the bottom of the opening O,with theinside edges of the door-frame atthe sides of the latter resting upon the underlap U of the rabbets b andthe inside bottom edges of the frame will rest upon the underlap U ofthe rabbet b To secure the frame within the opening 0 and firmly connectit with the base, stovebolts m are passed through the bolt-passages aformed in the frame F at the bottom corners thereof and also between thelugs R R. arranged in the base at the bottom of the opening 0, to besecured therein by nuts straddling the lugs, and a bolt m connecting thebolt-ear with the lug R on the framebottom, with stove-bolts passingthrough the top of the door-frame bolt-passages i t to em ter the lugs mm, formed in the top plate P.

The letters L designate the stove-legs, on which the base is supported,and they connect with the base in the usual manner.

The letters N designate the shaker door, which at its lower edge 7L2 ishinged to the exterior of the door D, immediately below theshaker-opening S formed in the upper part of the door.

The letter Y designates a yoke which at its ends is secured to the innerface of the door D by means of screw-bolts s and at each side of theopening S and between its ends where extended downwardly it is made toextend laterally, so as to be in line with the bottom of the opening Sto form a support for the grate-shaker when entered through the open ingS to engage with the end of the shaking bar 9 The letters 1; designateshelves which are integrally cast with the base, and they haveupwardly-projected pins 12 and are arranged to receive the ring in whichthe stove-grate is mounted.

.The letters d cl designate plates which are arranged on the inner edgeof the top T, and these plates are made separately from the base and areconnected thereto by screwbolts 0 These plates support the grate-ringand act as ash-deflecting plates.

A stove base having its apron, together with its ash-pit, castintegrally with the front opening for the ash-pit door-frame having itssides and bottom formed in the apron and ash-pit at the front, with thisopening so inclosed at the bottom and sides and continued up through thebase-top, to be completed by the insertion and connection of the ash-pitdoor-frame by means of the interposition of the plate P,with the latterand the top of the door-frame connecting with the omitted parts of therings J and J so as to complete the latter, as herein shown anddescribed, greatly facilitates the proper mounting of the doorframe,simplifies the molding of the parts, and makes the chances of losing thecastings in the sand much less than where the top as well as the bottomof the opening are all made integrally with the ash pit and the apron,

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is-

1. The combination with a stove-base having its apron, ash-pit, and topcast inone piece, said base being cast with an open-topdoorway openingfor the ash-pit door, and provided with a ledge at the top of each sidea of said doorway-opening; of aseparately-cast top plate constructed toconnect at each of its ends with one of the ledges at each side, and atthe top of said doorway-opening substantially as shown and described.

2. The combination with a stove-base having its top, its apron andash-pit cast in one piece and so as to inclose at the front the bottomsand sides of an open-top doorway for the ash-pit door, of a top plateseparately cast,

, and constructed to connect with the base at each side of said doorwayby means of ledges formed in the base thereat, and thus form the top ofsaid doorway, and an ashpit door frame provided with an inturned upperedge, with said frame constructed to be entered within said doorway andthereat connected to said base, with the inturned edge of saiddoor-frame overlapping said top plate to rest thereon and connectedthereto substantially as and for the purposes set forth.

The combination with a stove-base having its top, its apron, and ash-pitcast in one piece, and so as to inclose at the base-front the sides andbottom of an open-top doorway for the ash-pitdoor, and having a ledge orshelf projected inwardly from the top of the apron at each side of thedoorway, with the latter provided at its sides and bottom with rabbetededges; of a separately-cast top plate constructed to connect at each ofits ends with one of said ledges, and thus form the top door, with therings in the top plateintermediately forming the fire-pot seat continuedto the edges of the doorway; of a separately-cast top plate constructedto connect with the sides of said doorway at the top of the apron; saidtop plate having an upcast inner edge which when said top plate isconnected to the base will be in circular alinement with the inner ringpartof the fire-pot groove; and a door-frame having upon its upper edgean up cast flange which when said door-frame is in-' serted in andconnected to the sides and bottom of said doorway and said top plate theflange part of said door-frame will form a continuation of theouter-ring of the firepot groove substantially as shown and described.

5. The combination with a stove-base havingits'apron G, its ash-pit A,and top T, having the upcast ring parts 3', and J and ledges Z, all castin one piece, and so as to inclose at the base-front the sides f andbottom f, of the opening 0 of the separately-cast top plate P,constructed to connect with said ledges, and having the upcast ring partE, which latter will be in circular alinement with the ring part J whensaid top plate is attached to said base; and the door-frame F,

having the inturned edge E, with said frame constructed to be attachedto said base within said opening 0, with its inturned part I overlappingsaid top plate P, and connected thereto, and its ring or flange part E,abutting against the ends of the ring part J, substantially as and forthe purposes set forth.
